Atomic time clocks use the latest satellite technology so they can connect and synchronize time to the atomic clock. The benefit is that the time clock never needs resetting, so there is less work involved in maintaining it.

Time Clocks are designed to stamp employee time cards and are straightforward to use. When the empoyee arrives they PUNCH IN and when they leave they PUNCH OUT.

Biometric Time Clocks

Biometric time clocks and attendance systems overcome the main disadvantage of simple electronic time clock being they are subject to errors from inaccurate employee time cards and in particular from so-called “buddy punching”, where one employeee punches the time clock for another employee.

A biometric time clock can use a handprint, or fingerprint or even retina scan system to verify employees’ identities in less than one second, based on their unique characteristics - such as the size and shape of their hands.

A biometric time clock is efficient to administer because there are no cards to create, administer, carry, or lose.

A biometric time clock costs more than a simple electronic time clock, but it returns the investment because it eliminates the costs associated with administrating and managing cards and stops buddy punching and time fraud.

I’m fascinated by clocks of all types. I think because the sound of clocks was always in the background when I was growing up. My German grandparents had a beautifully carved cuckoo clock, my English grandparents had a grandfather clock which chimed every quarter hour, my own parents had a mantel clock that had pride of place over the fire and I slept soundly every night soothed by the steady ticking of my bedside alarm clock.   

My children now check the time on their mobile phones or in the bottom corner of the PC screen. I love the sight and sound of clocks in public places - Big Ben’s chimes are another fond memory.

Anyway, back to making a potato clock - here are the instructions.

How and why does a Potato Clock work?

The potatoes actually form an electrochemical battery, also known as an electrochemical cell. Basically, the electrochemical cell converts chemical energy to electric energy by a spontaneous electron transfer.

In the particular case of the potato, the zinc in the galvanised nail reacts with the copper wire, with the potato acting as a buffer between the zinc ions and the copper ions.

If the zinc and copper ions touched within the potato they would react but only generate heat. The role of the potato is to keep them apart, so the electron transfer has to take place via the copper wires of the circuit, which channels the electron flow i.e. electricity into the clock.

Supplies Required for the Potato Clock

• two potatoes
• two common galvanized nails
• three pairs of alligator clips connected to one another with wire
• two short pieces of heavy copper wire
• a simple low-voltage LED clock unit that functions from the power of a 1 to 2 volt, button-type battery

Potato Clock Assembly Steps

1. Open the LCD clock battery compartment and remove the battery.
   (Note that there is a positive (+) and a negative (-) terminal point where the battery was installed.)
2. Insert one galvanised nail into each of the potatoes.
3. Insert one of the short pieces of heavy copper wire into each potato, locating it as far from the nail as possible.
4. Use one alligator clipto connect the copper wire inserted in one potato to the positive terminal in the clock unit.
5. Use one alligator clip to link the galvanised nail in the other potato to the negative terminal in the clock unit.
6. Use the final alligator clip to link the spare galvanised nail in the one potato to the spare copper wire in the other potato.
7. Set the clock and you’ve finished.

A song written in 1875 called “The Grandfather’s Clock” told the story of an aging floor clock that stood in the George Hotel in North Yorkshire, England. Two brothers managed the hotel. The clock began slowly losing time immediately upon the death of one of the brothers, and upon the death of the second brother, the floor clock stopped working altogether despite numerous attempts to have the clock repaired.

Eventually new management gained control of the George Hotel, but the clock remained in place as a tribute to the two brothers who had faithfully managed the hotel for so many years. The term “grandfather clock” caught on quickly after the song became widely known and since then, what were originally known as floor clocks are commonly called Grandfather Clocks and are a cherished part of our culture.

Over the years there have been numerous improvements to time-keeping devices and grandfather clocks are no exception. In modern times, a grandfather clock is a statement of excellent taste and firmly rooted tradition.

Grandfather clocks are commonly a family heirloom that is passed down through the generations. Grandfather clocks vary somewhat in size, but are generally 6 to eight feet tall and lend a stately appearance to any room. You can also find smaller versions of grandfather clocks, which are known as grandmother and granddaughter clocks.

Families for centuries have passed a cherished grandfather clock from one generation to the next, and today there are grandfather clocks with great historical and sentimental value. Some of the oldest known grandfather clocks are still used as the models for the grandfather clocks we purchase today. You will also be able to find more modern version of the grandfather clock in varying styles and colors.

Each time you see a grandfather clock, remind yourself of where this term originated and give a bit of thought to the long history of these treasured timepieces and heirlooms. If you do not own a grandfather clock you will be happy to know that it is easy to start your own family heirloom and you will be able to find the perfect grandfather clock in all price ranges.

Mr Piekarski says one of his biggest challenges in owning the clocks is getting ready to spend 12 hours either rewinding or fast-forwarding his collection of cuckoo clocks when British Summer Time begins or ends.

Typically he says it takes him about 12 hours to reset the time on all of his 561 clocks each time the time changes.

Mr Piekarski runs the Cuckooland Museum with his brother, Maz. Both men trained as clock-makers from an early age, starting in Manchester when they were 15. They started their interest in cuckoo clocks soon after and set up the museum in 1990 after they had built up their world class collection of clocks.

Some of their cuckoo clocks are very rare:
- They have antique clocks from the Black Forest.
- Their collection has clocks with quails and monks playing bells instead of the usual cuckoos.
- They also have a ‘cuckoo and echo’ clock that emulates the whistles and bellows a cuckoo makes in the wild and is thought to be one of only six in the world.

These clocks are collector items and change hands for a high price. It is now possible to check that your clock has the correct parts — the hands and the pendulum in particular. Jerry Maltz has devoted 25 years to the collecting and research of clocks manufactured by Edward Payson Baird and published his research in a 200 page book devoted to these clocks, complete with photographs.
